3e it known that LF AN Dohzowrrorr, citizen f the United States, residing Wilkes-Barre, in the county of Luzerne and State of lxemisylvania, have inyented a new and useful sparkukrrester, of which thefol lt'ming' is a specification.

This invention relates pletely within the smoke box of the locomotire and whereby sparks and Cinders "are trapped before reaching the smoke pipe and are. retainedfat a point where theyscan be conveniently reached and removed. A further ob'cct is to provide an-jarrester which will not interferewithf the draft through the boiler. i

Vith the foregoing.. andig'other objects view which willfa'ppear as the description proceeds, the invention" resides in thehe'o n' bination'and arrangement of parts an din the details of construction hereinafter gde 4 is a sectidn on line,-C1'-D Fig-i2 2.

Another segmental partition 10 is arranged within the smoke box and is preferably parallel with, the partition 8, this partition 10 being extended upwardly from one wall of the cinder box 6 and being provided, along its upper edge, with a depending inclined apron '11 discharging downwardly into a trough 12 which extends transversely of the smoke box and has its bottominclined downwardly to a discharge spout 13.

I The spacebetween the partitions Sand 10 is divided by a partition 14:,into compartand 16, the said compartment 16 ,ment v receiviiig the -cinders discharged from the sp iiut i3 whilefthe compartment 15 receives {any cinders which, may be carried down- ;wardly between partition 8 and bathe plate 9. The upper" portion of partitionll' is inclinecl laterally and upwardly, as shown at 1 1? while the lower or substantially vertical portion of the partition 14 laps a partition 5 17 which extends downwardly into the cin der box 6. ,An inclined s 'cre enlS extends from the upper edge of the hopper 12 to the iitop of the smoke box and overhangsthe partition 10.

It will be apparent'that when the products of. combustion issue from, the boiler 1,

w they will be deflected by the partition 8 and 1. r partly/in eleva tig i' and partly] inQSeQ'trd-ai baflle plate-3'9 and pass downwardly as indicated by the arrow in the drawings so that sparks and cinde'rs will thus be directed downwardly into the compartment 15 and fall into the cinder box'6. The gasesand 'lighterpa rticles will flow outwardly over the partition 10 and through the screen 18, any sparks and cinders coming into contact with the screen being deflected downwardly and guided by the apron 11 into the hopper 12. From this hopper the said cinders, etc.,

will gravitate into compartment 16 and thence into. the box 6. By opening the bot-' .tom of the cinder box the contentsof said box can be removed. 4

It will be seen that a device such as herein described constitutes efiieient means for stopping sparks'and cinders so that they will not e ejected-through the pipe or stack 8. Furthermore, the device will not retard the circulation of the combustion products to an undesirable extent. By havingthe partition 8 bridge thebox 6, any portion of the combustion products which maybe deflected downwardly will be free to pass into the box 6 and thence upw ardlybetween the two partitions 8 and 10,

Whatis claimed is 1. The combination with the smoke .box

of a boiler, of a spark arrester therein and,

extendinginto the path of the combustion productaismd, spark arresterincluding a cinder "box, spaced artitions above the cinder box, and spaced from" the topofthe'smoke-box, a baflie de- 1 pending-lfirom the top of the smoke box and etweengthe'partitions, a hopper, a screen extending from the hopper tothe top ,of the smoke'box and intersecting the path of the products'pf combustion from between the partitions, the said hopper discharging into the spaceebetween the partitions.

2. The combination with the smoke box of a boileij'of a sparkarrester including a cinder 'box,'-' transverse partitions within the smoke box and above the cinder box, said partitions being spaced from the top of the smoke box, a bafile plate depending from the top of the smoke box and between the partitions, ahopper supported one of the partitions, a screen extending from the ho per to the top of the cinder box and across t e ath ofthe products of combustion flowing rom between the transverse partitions, said hopper discharging into the space between the partiti ons, and a partition connecting the transat their upper edges.

verse partitions and dividing the space".

therebetwee'n into separate compartments opening downwardly into the cinder box.

3. The combination with the smoke box of a boiler, of a. s ark arrester including a cinder box depen ing from the smoke box and having a bottomadapted to be opened,

spaced transverse partitions above the cinder box, a'partition connecting the said transverse partitions and dividing, the space therebetween 'into upper and lower compartments discharging downwardly into the cinder box, a baflie plate depending from Y the top of the smoke box and intersecting I the path of the products of combustion issu- 'ing from the compartment. I

In testimony that I claim the foregoing as my own, I havehereto eflixed my signaturein the presenceof two witnesses. V
